About Us

Established in 1990.

Boston Diamond Studio ( DBA: Platinum Studio) is a boutique jewelry studio in the heart of Jewelers Building in Downtown Boston. We are in our third decade of doing business and have grown tremendously during a stretch of time when most have seen a decline in their business.

We operate our business by gaining your trust and offering you the best quality items at truly the lowest purchase prices. What further sets us apart is the fact that our roots are in the design and manufacturing of fine jewelry.

We are the only jewelry studio that has the capability to design and manufacture your desired ring in house. We also specialize in restoration of precious metal gold and platinum using the highest quality diamonds and gemstones from around the world.

We are a family owned small business who thrives on customer satisfaction and guarantees the highest quality with integrity and honesty.
